rybitski 0 Report post Posted June 28, 2006 I'm looking for a drill press design for drilling pcb using a dremel, any ideas?I think this has already been done some where, but why not disscuss it? Besides, It kind of dissapoints me that the hardware section is kind of empty... :'( Quote Share this post Link to post Share on other sites
rybitski 0 Report post Posted June 28, 2006 Here is my design.I have started building it and I would say that I am 3/4ths of the way done with it... I'll post pictures later.Comments/ improvements on my design are welcome ;D Quote Share this post Link to post Share on other sites

gogo2520 1 Report post Posted June 29, 2006 Hello rybitski Dremel all ready makes a small drill press stand that you can attach you drill to. It only cost about 30 bucks and it pretty sturdy, don't know I guess if you can come up with something better for less that might be good. I bought a cheep drill press for under a 100 bucks, a small benchtop one. Best 100 bucks I ever spent. Have fun gogo Quote Share this post Link to post Share on other sites
rybitski 0 Report post Posted June 29, 2006 But think, that $30 I just saved went towards buying more pcb supplies, or better yet, That variable temperature soldering iron that I've always wanted... In my search I did run across the Dremel press (for $30 as you mentioned), but making something is always more fun? :) Quote Share this post Link to post Share on other sites
ante 2 Report post Posted June 30, 2006 I scrapped an old Mustek scanner a few weeks ago and I can see you could have use for some scanner parts here. Inside it was two fine rods and slide bearings to match! ;) Quote Share this post Link to post Share on other sites
rybitski 0 Report post Posted June 30, 2006 I am actually using 2 printer rods with the copper bearings...Right now the project has come to a hault because someone has stolen my drill bits and the ones I have (that werent stolen) aren't the right size...

rybitski 0 Report post Posted June 30, 2006 I was using an off brand dremel tool with a grind stone attached to it... Result: I broke the drive transmission, which is only a spring... Maybe since I broke my rotary tool I don't need that drill press any more.I kind of fixed it, but it is a little bit off balance, so at high speeds the tool vibrates alot. :'(Someone gave me an old Musket scanner, a very compact unit. Mine only had 1 bar...And just think, our own modderator throwing out a perfectly re-usable scanner.... ;D Quote Share this post Link to post Share on other sites
ante 2 Report post Posted June 30, 2006 Yeah, the mechanical parts where fine but the scanner sent out smoke signals after the wall wart got faulty serving 30 Volts to the unit in stead of 16! A pcb with plenty of surface mounts got fried and I signed the death certificate immediately! I saved the plastic covers, the glass and the lid for a future project, a UV light box.B T W, 100 posts….. You are now a full member Chris!

rybitski 0 Report post Posted July 1, 2006 Ok, so here it is... (so far)The actual mountfor the dremel is not yet made and It needs another lever arm on the oposite side to keep it from binding. I put some springs on the rods and they work great (thanks for the suggestion sarathk) ;)SO that is the update, again any comments/ improvements are welcome ;D Quote Share this post Link to post Share on other sites
ante 2 Report post Posted July 1, 2006 Another lever arm might not prevent the thing from sticking. The picture is not clear enough to show if any of the joints (screws) have some sideways slack, it should have because the distance between the two screws varies as the tool holder slides up and down. ???

rybitski 0 Report post Posted July 1, 2006 I think it will help because, when you push down with even force on both sides of the 'trolley' as I like to call it, it moves up and down smoothly.he picture is not clear enough to show if any of the joints (screws) have some sideways slack, it should have because the distance between the two screws varies as the tool holder slides up and down. ???I'm not sure what you mean by this, could you please explain.

ante 2 Report post Posted July 1, 2006 When I magnified the pic I could see you got it right! If you need it to push on both sides make the lever arm in one piece (U-shape) and put a hinge on the back of the press, something like this:The red thing is supposed to be a hinge, the blue is the lever and the view is from above! ;D Quote Share this post Link to post Share on other sites
rybitski 0 Report post Posted July 1, 2006 Sorry for the bad picture... So you were talking about cutting the slot in the lever arm for the screw to slide back and forth in. I really like your idea of haning them connect form bhind (I was going to connect them from the front). Quote Share this post Link to post Share on other sites
ante 2 Report post Posted July 2, 2006 Yes, that’s what I was thinking about. Not a bad picture, just small! ;DLet us know how it develops! Quote Share this post Link to post Share on other sites
rybitski 0 Report post Posted July 2, 2006 I have a bad habbit of starting too many projects at one time and then taking a while to get them all finished... :-\ So I kind of put this project on hold because I wanted to make a laser show (mirrors attached to spining motors to manipulate a laser)... It will get finished, just not right away...Projects I am working on: (or lack of working on)Pool pump controlMini drill pressLaser showElectronic jewelry thingscleaning the work shop555 timer based metrenomevarious other things I get distracted with...The PCB keychains I make (and try to sell) on my website got some recognition this morning on hackedgadgets.com, take a look: http://hackedgadgets.com/2006/07/02/pcb-keychain/#more-353ANYWAY, I'll be sure to update with pictures when something interesting happens with this project. :) Quote Share this post Link to post Share on other sites

Omni 2 Report post Posted May 4, 2007 Hi blueroomelectronics,The type drill press you provided in the pic is not a good choice for PCB drilling.Remember, when looking at a press other than a dremel always firmly grab the chuck (jaw) and shake it to feel if their is ANY horizontal movement.Typically, PCB drilling requires an index from #55 - #60 which are extremely thin bits/rasps.Any horizontal movement concerning the chuck can easily cause a distorted hole.The picture you provided (drill press) is more oriented to chassis hole drilling etc...A dremel is the perfect drill for PCB use since the chuck is directly connected to the motor shaft.Furthermore, purchase the dremel press since it is matched for the dremel drill!Honestly, i like to use a dremel off of the press (hand use) since i can achieve a good feel for required pressure.However, if you plan to use a dremel (hand use) always make sure your drilling is a straight pass through the PCB, avoid any angle etc...

blueroomelectronics 0 Report post Posted May 4, 2007 True, a high speed bit like a dremmel would be much better. I've not drilled my own PCBs in years. Quote Share this post Link to post Share on other sites
